Description

[0001] Device for carrying and / or receiving a load and method for connecting a component to a connecting element

[0002]

[0001] The invention relates to a device for carrying and / or receiving a load, wherein the device comprises at least one component, a connecting element and at least one externally accessible opening for introducing an adhesive, and at least one sealing element is arranged between the component and the connecting element. The invention further relates to a method for connecting a component to a connecting element.

[0003]

[0002] Components that permanently bear a load, such as support beams in buildings, or that temporarily bear a load, such as a bicycle frame, are often joined with other connecting elements. In principle, different types of connections can be used for joining. With positive-locking connections, such as rivets and screws, there is a risk that the separate connecting element will loosen over time under corresponding stresses, such as vibrations. A further disadvantage is that the component and / or connecting element no longer has a smooth, closed surface, which can lead to functional limitations and / or material damage, such as corrosion.

[0003] When welding is used as a material-bonded connection of load-bearing components, the following disadvantages are distortion in the component due to heat input, the formation of a predetermined breaking point around the weld seam, and the fact that loosening is only possible by destroying the components.In conventional adhesive bonding, the adhesive is typically applied separately to one surface of the component and the mating part, and then the two are joined. This carries the risk of the adhesive being uncontrollably scraped off and / or pushed away from the surface. As a result, the required adhesive gap cannot be reliably maintained at the bonding point. Furthermore, due to the manual application of the adhesive, precise application and formation of the bond between identical components and / or in series production are only achievable with limited repeatability and process reliability.

[0004]

[0004] Furthermore, methods are known from the prior art in which pipes and sockets are inserted into one another, thereby creating an annular cavity (adhesive chamber) into which an adhesive is injected. A disadvantage of this method is the lack of process reliability in industrial series production. In purely passive adhesive chambers formed solely by insertion, manufacturing tolerances of the pipes and sockets lead to asymmetrical adhesive gaps, which compromise the structural integrity and long-term strength of the adhesive bond. Moreover, a reliable seal of the chamber against uncontrolled adhesive leakage and permanent galvanic isolation (prevention of contact corrosion) with different material pairings (e.g., carbon / aluminum) cannot be reliably achieved using conventional methods.

[0005]

[0005] US Patent 2019 / 0 1844 65 A1 discloses a device and a method with a node-pipe connector in which a node surrounded by a pipe is divided into three adhesive channels formed between sealing surfaces of the node and an inner wall of the pipe. Each sealing surface is bounded by opposing O-rings, with an adhesive chamber formed between each O-ring. The adhesive chambers are connected by means of adhesive channels, which enable a closed adhesive flow path between two external connections in the node. Under vacuum, the adhesive channels are used stepwise to fill the sealed adhesive chambers.

[0006]

[0006] DE 10 2023 127 717 relates to an adhesive joining of beam and node elements, wherein at least one beam or node has an opening for introducing a structural adhesive, which opens into a gap of a cylindrical interface between the inside of the node and the beam to which it is attached. The node may also have an air release opening. An internal structure of the node, against which a distal end of the beam abuts, serves as a reference point for correct alignment of the beam and the node relative to each other.

[0007] EP 3 632 777 A1 describes a vehicle chassis with connecting tubes joined by one or more nodes. A seal may be attached to a connecting projection of a connecting body, with the connecting tube being placed onto the inner projection. Adhesive is injected between a surface of the inner projection of the connecting body and an inner surface of the respective connecting tube, for which purpose the connecting body may have an opening or a vacuum connection.

[0007]

[0008] The purpose of the invention is to improve the state of the art.

[0008]

[0009] The problem is solved by a device for carrying and / or receiving a load, wherein the device has at least one component, a connecting element and at least one externally accessible opening for introducing an adhesive, and wherein at least one sealing element is arranged between the component and the connecting element, wherein the device has an adhesive chamber filled with an adhesive, bounded by a surface of the component, a surface of the connecting element and a surface of the at least one sealing element, such that the component and the connecting element are bonded together by means of the adhesive in the adhesive chamber, and wherein the device has at least one insert, wherein the at least one insert is arranged in and / or on the adhesive chamber at least partially between the component and the connecting element.

[0010] Thus, a device is provided in which a defined, durable, and materially bonded connection between the component and the connecting element is formed by means of a spatially limited and sealed adhesive chamber, precisely aligned between at least one surface of the component and a surface of the connecting element. It is particularly advantageous that the spatial arrangement and geometric design of the at least one insert ensure that the required adhesive layer thickness is maintained across the entire bonding surface between the component and the connecting element. Furthermore, the adhesive chamber is specifically designed, varying in its properties such as volume and shape, and can be flexibly configured by means of the at least one insert and adapted to the respective component and / or connecting element.In this process, at least one insert and / or at least one seal is in contact with the adhesive in the bonding chamber, at least partially, for example, on a section of its surface. The component and the connecting element can be precisely aligned relative to each other by means of the at least one insert and / or the at least one seal, so that the bonding chamber can be reproducibly configured even in the production of repetitive devices and / or in series production, thereby providing a reproducible, secure, long-lasting, material-bonded connection.

[0009]

[0011] The adhesive chamber, defined by the at least one insert, allows for precise control of the required adhesive volume. This prevents overdosing, unwanted oozing of the adhesive, and smearing on the outer surface of the component and / or the connecting element. Because the at least one seal and optionally the at least one insert have elastic properties, a slight overdosing of the adhesive is compensated for by the deflection of the sealing element and optionally the insert at the edge of the adhesive chamber, thus preventing over- and oozing of the adhesive. Consequently, cleaning of excess adhesive residue is unnecessary with the device and method according to the invention.

[0010]

[0012] Furthermore, by positioning the at least one insert and / or the at least one sealing element and their respective material thickness, contact between the materials of the component and the connecting element can be specifically prevented. Thus, even a component and a connecting element made of mutually incompatible materials can be securely and durably joined using the filled adhesive chamber.

[0011]

[0013] Furthermore, the enclosed adhesive chamber between the component, the connecting element, and the at least one sealing element enables the device and its components to be repaired and recycled. This is achieved by non-destructively breaking the bond through selective or complete heating of the adhesive within the chamber. After breaking the bond, the component, the connecting element, and the at least one insert are available again individually and unchanged, and can be reused or recycled. Breaking the bond is possible for components, connecting elements, and, if applicable, inserts whose melting point is significantly above the vaporization point of the respective adhesive. This is the case, for example, when the component and the connecting element are made of isotropic materials such as metal.

[0012]

[0014] A key aspect of the invention is based on preventing accidental bonding errors during the joining of the component to the connecting element by means of at least one insert, which creates a spatially defined, enclosed bonding chamber according to the Poka-Yoke concept. This ensures a durable, resilient, and materially bonded connection between the component and the connecting element. Thus, a cost-effective, flexible, and modularly adaptable, process-reliable, repairable, and recyclable device and corresponding method are provided, in which the component, the connecting element, and the at least one insert can have freely varying designs and material properties, consequently allowing for a multitude of different devices.

[0015] It is particularly advantageous that the at least one insert, acting as a multifunctional and process-defining interface element, provides a flexibly adaptable, intelligent assembly and joining system for components and fasteners, enabling a reliable, high-precision adhesive bond. The at least one insert allows for immediate mechanical fixation of the component and the fastener. This ensures immediate handling strength, particularly through press fit, of the entire structure during assembly, without the need for external fixing devices. Furthermore, the at least one insert compensates for tolerances, thus decoupling manufacturing tolerances of the component and / or fastener.Another advantageous function of the insert is the sealing and insulating function with a sealing of the adhesive chamber and / or the adhesive space and a forced decoupling to prevent contact corrosion between the component and the connecting element.

[0013]

[0016] The following terms will be explained:

[0014]

[0017] A "device" can be any type of apparatus in which at least one component, at least one connecting element, and at least one insert with an integrated sealing element or with at least one separate sealing element are arranged such that they define an adhesive chamber. By filling the adhesive chamber with an adhesive, the component and the connecting element are bonded to each other, and the at least one insert and, optionally, the at least one sealing element are bonded together in a materially bonded manner. The device can be a structural component, an assembly, a device, a machine, apparatus, or a system. For example, the device can be a frame device or a linear profile device.A device can be, for example, a piece of sports equipment, a furniture frame, a railing, a staircase or facade element, a bicycle frame or crankset, an orthotic measurement system in medical technology, or a fitting. A device can also be a modular chassis for vehicles with and without integrated crash absorbers and / or stabilizers, a manufacturing device, for example, for further processing vehicle parts such as cockpits or bodies, or a wind turbine rotor. A device can also be a base frame with integrated damping, for example, for forging and forming tools to prevent vibrations, or a modular support frame for household appliances such as washing machines, refrigerators, or ovens. Naturally, the device can also have two or more adhesive chambers.

[0015]

[0018] A "component" is, in particular, a part of a device. A component can be, for example, a tube, a beam, a hollow profile, or a profile. In principle, the component can have any three-dimensional shape, any cross-sectional shape, and / or any material. The component can be adapted in its design and / or properties for the material-bonded connection using the adhesive chamber. Preferably, the component is a component manufactured for its function and is not further adapted for the material-bonded connection using the adhesive chamber. The component can be manufactured, for example, by forming and / or hydroforming. For example, the component can be a hydroformed, ovalized tube whose wall thickness is adjusted by drawing it along its length.The component is connected to the connecting element at at least one end and / or end section. The component may also have at least a partial cavity within it, in which the connecting element is at least partially contained. The surface of the component may be an external or internal surface. A surface may also be only a section along one side of the component.

[0016]

[0019] The "connecting element" (also called "connecting part" or "node") is a component of the device that is or will be materially connected to the component. The connecting element can have any design and shape. For example, it can be an angle connector, T-connector, cross connector, multi-way corner connector, or connector with an adjustable angle joint. The connecting element can also be an end piece, a connector with a flange and / or base plate, a connector with an adjusting ring eye or hinged corner pieces, and similar components. The connecting element can be manufactured by primary forming processes such as casting, forming processes such as forging, and / or intermediate processes such as thixomolding. Machining processes can also be used to shape the device and create functional surfaces.To specifically design the connecting element for the material-bonded connection using the adhesive chamber, the connecting element is preferably manufactured using additive manufacturing technology, for example, powder bed fusion laser sintering, binder jetting, or selective laser sintering. Thus, the connecting element is preferably specifically adapted to form the adhesive chamber. If the at least one opening is not formed by the arrangement of the component and the connecting element relative to each other, the connecting element can have the at least one opening. This can be created, for example, by drilling or milling. Likewise, the connecting element can have an injection channel for the flow of the adhesive, which is arranged internally between the at least one opening and the adhesive chamber.The fastener can also have a specific guide geometry to ensure reliable assembly and / or joining to and / or with the component. The fastener and / or the component can, in principle, be made of any material, such as metal, light metal (like titanium, magnesium, and aluminum) and their alloys, plastic, composite material, and / or fiber-reinforced plastic. The fastener is designed in such a way as to adhere to the Poka-Yoke principle. The surface of the fastener can be an external or internal surface. A surface can also be just a section along one side of the fastener. The fastener can be partially embedded within the component, or it can be partially or completely located on or around the outside of the component.

[0017]

[0020] The "insert," also called an "inlay," is a shaped piece positioned between the component and the fastener. The insert prevents direct contact between the component and the fastener. This prevents corrosion, for example, when the component and fastener are made of incompatible materials. The insert is typically placed loosely and / or inserted into the component and fastener. Alternatively, the insert can be attached to the fastener before it is attached to and / or inserted into the component and before bonding. In this case, the insert also acts as a spacer. If the insert is partially positioned between the component and the fastener, space adjacent to its end can be reserved for filling the adhesive chamber.The insert is at least partially arranged in and / or on the adhesive chamber, for example, with one of its outer surfaces, and thus defines the adhesive chamber with its section and / or surface. In this way, the insert acts as a spacer between metals with different electronegativity and thus provides galvanic isolation. The insert is made of a non-conductive material, such as plastic or ceramic. Preferably, the insert has a strength that is at least somewhat lower than the material strength of the component and / or connecting element. The stronger the selected material of the insert, the better the insert aligns the component and the connecting element relative to each other. Conversely, a softer material for the insert offers greater tolerance compensation capabilities and / or a better sealing function.The insert can be made of a thermoplastic or thermosetting plastic such as PA, PP, PC, PE, PET, PVC, PMMA, TPU, PU, ​​Bakelite, epoxy resin, PUR, and / or aminoplastics. It can also be made of an elastomer such as NBR, FKM, or silicone. Alternatively, the insert can be made of a light metal, particularly if the light metal does not react galvanically with the materials of the component or connecting element, and / or a composite material. For example, the insert can be monolithically made of hard rubber / TPU.Two or more insert components, spaced apart along a surface of the fastener and / or the component, reliably prevent contact between the fastener and the component and establish a uniform distance between them across a dimension, such as a length or cross-section, of the fastener and / or the component, thus creating a homogeneous adhesive gap and / or a homogeneous adhesive chamber. The two or more inserted components can have the same or different properties, such as material, shape, and size. The minimum insert component can be one-piece, two-piece, or multi-piece.

[0018]

[0021] An "opening" is, in particular, a free diameter and / or passage. The opening is or is formed, in particular, by the arrangement of the component, the connecting element, the at least one insert, and / or the at least one seal. In an elongated device, for example, the component, the connecting element, the at least one insert, and the at least one seal can be arranged such that an opening connected to an inner cavity between the component and the connecting element is formed at each end of the elongated device. Likewise, the at least one opening can be provided in the outer surface of the component, the connecting element, and / or the at least one insert. Preferably, the at least one opening is provided in the at least one insert.Thus, the at least one opening is specifically designed as a recess and / or opening through a material thickness of the component, the connecting element, and / or the at least one insert. An opening can also be a drilled hole. The opening can also have a conical depression on its outer surface. Preferably, the device has at least two openings, one for introducing the adhesive (filling opening) and the other for venting the adhesive chamber (outlet opening). The adhesive level can thus be monitored through and / or in the outlet opening. Preferably, these two openings are arranged on opposite sides of the adhesive chamber. Each of the two openings can open directly into the adhesive chamber or be connected to it via an injection channel (feed or outlet channel).By filling the adhesive chamber, the respective opening is filled with adhesive. After the adhesive has been introduced, the respective opening can also be selectively closed by means of an additional closure, for example by inserting a plastic plug into the recess of the opening, preferably flush with the outer surface of the device. In principle, the diameter and / or length of the respective opening can be freely selected. Preferably, the filling opening and the outlet opening have the same diameter. However, the outlet opening can also have a smaller diameter and thus build up increasing back pressure when the adhesive chamber is filled under pressure.

[0019]

[0022] To simplify the filling process, the dimensions of the filling opening and the outlet can be adapted to an application nozzle for single-component adhesives or a mixing nozzle for multi-component adhesives. The openings, and optionally the channels located between each opening and the adhesive chamber, are designed and configured with hydraulic balancing to prevent pressure loss during filling.

[0020]

[0023] An adhesive (also called a bonding agent) is, in particular, a non-metallic process material that bonds other materials through surface adhesion and its own strength (cohesion). In addition to absorbing tensile and / or shear forces, the adhesive can also dampen vibrations, seal against gases and / or liquids, prevent corrosion, and / or insulate against electrical voltage and / or temperature. The adhesive is typically a chemically curing adhesive. An adhesive can also be a structural adhesive, which ensures reliable, long-lasting bonding and sealing even under load-bearing and / or mechanical stress.The adhesive can be, for example, a two-component epoxy adhesive that cures within 5 to 8 minutes and allows further mechanical processing of the device after one hour. The adhesive can be selected and used in such a way that it has a melting point below that of the materials of the component, the connecting element, and the at least one seal. For example, heating an adhesive to 220 °C for 15 minutes can cause it to evaporate, allowing the component and the connecting element to be separated without damage and subsequently repaired, reused, or recycled.The term "materially bonded connection" refers in particular to a connection in which the joining partners, and thus the adhesive, the component, the connecting element, the at least one insert and the at least one sealing element, are held together by atomic or molecular forces.

[0021]

[0024] The "adhesive chamber" (also called "adhesive space") is, in particular, a free space and / or installation space arranged between the respective surfaces of the component, the connecting element, the at least one insert, and the at least one sealing element. The adhesive chamber is, in particular, filled with air and / or gas before being filled with the adhesive. In the device, the adhesive chamber is already filled with the adhesive and preferably no longer contains air and / or gas. The shape and / or dimensions of the adhesive chamber are freely selectable, but are limited by the geometric design of the component, the connecting element, the at least one insert, and the at least one sealing element. The adhesive chamber is connected to the at least one opening accessible from the outside.Preferably, the adhesive chamber is connected to the filling opening and the outlet opening, in particular via at least one channel (injection and / or venting channel). The adhesive chamber has, in particular, a precisely defined adhesive gap for the respective adhesive required between the surface of the component and the surface of the fastener. The precisely defined, homogeneous adhesive gap is ensured, in particular, by one or two or more inserts.

[0022]

[0025] The dimensions of the adhesive chamber can also be designed, or are designed, according to the Poka-Yoke concept to prevent an insufficient adhesive gap as a potential source of defects. For a high-strength or high-durability bond, for example, using epoxy or polyurethane adhesive, the dimensions of the adhesive chamber are specifically designed to create a small adhesive gap of < 0.50 mm, particularly within a range of 0.10 mm to 0.45 mm. For a semi-structural, material-bonded bond with a polyurethane adhesive, the adhesive chamber is specifically designed to create an adhesive gap between 0.5 mm and 3.0 mm. This ensures an elastic bond with damping and / or crash absorption properties.For an elastic connection between the component and the connecting element with even stronger damping and / or crash absorption properties, a bonding gap of > 3.0 to 10.0 mm, preferably 4.0 to 8.0 mm, and particularly preferably 5.0 to 6.0 mm, is set by means of the bonding chamber when using polyurethane or silicone adhesives. Thus, the resulting bonding gap is precisely defined in advance, depending on the adhesive used, and set by adjusting the dimensions of the bonding chamber. Generally, the bonding and / or sealing gap is preferably in the range of 1.5 to 3.5 mm. The adhesive in the bonding chamber forms a material-bonded connection with the component, the connecting element, at least one insert, and at least one sealing element.Depending on the choice of material for the sealing element and / or the at least one insert, the elastic properties of the adhesive in the adhesive chamber and of the sealing element and / or the at least one insert can be enhanced and / or specifically used both when filling the adhesive chamber and during the subsequent use of the device for damping dynamic loads.

[0023]

[0026] A "sealing element" (also referred to as a "seal") is, in particular, an element, structure, or surface designed to prevent or limit unwanted material transfer from one location to another. The sealing element seals the component and the connecting part against each other and defines the inner adhesive chamber. To seal and define the adhesive chamber and / or to precisely align the connecting element and the component relative to each other in the device and / or during assembly, two or more sealing elements are preferably arranged and / or used. The sealing element can be, in particular, a static or a dynamic sealing element. A static sealing element can be, for example, a flat gasket, an O-ring, or a U-ring. A dynamic seal is, in particular, a bellows.A bellows is particularly advantageous when the sealing element, acting as a damper and / or crash absorber, is subject to significant axial deformation. The sealing element can also be lamellar and / or lip-shaped. The sealing element is typically assembled individually during the manufacturing process. In the case of a tubular component, the sealing element can, for example, be an O-ring slid onto the outer diameter of the tubular connecting part or onto the inner diameter of the component. Similarly, one, two, or more sealing elements can be arranged on the connecting element. When using two or more seals, the seals can be of the same type or of different designs. For example, the seals can be of the same type but have different cord lengths.The surface of the sealing element is, in particular, an outer surface. Preferably, the at least one sealing element is already arranged on the insert or integrated into the insert before assembly.

[0024]

[0027] Because the at least one sealing element and / or the at least one insert simultaneously provides a limiting surface to the adhesive chamber and a seal between the adhesive chamber, the component and / or the connecting part, the at least one sealing element and / or the at least one insert supports a complete, homogeneous filling of the adhesive chamber when filling it with the adhesive, as the at least one sealing element retains its sealing function.

[0028] The at least one seal can be located internally at the furthest point from the externally accessible opening for introducing the adhesive between the component and the connecting part, or in the at least one insert part, thereby enabling precise positioning of the component and the connecting element relative to each other and limiting the adhesive chamber.

[0025]

[0029] In another embodiment, the at least one insert part has or forms the at least one sealing element.

[0026]

[0030] Thus, the insert directly seals the adhesive chamber, between the component and the connecting part, and / or between the component and the at least one insert. This eliminates the need for either the component or the connecting element to have a seat for a sealing element, allowing for simpler and less complex design and manufacturing.

[0027]

[0031] In order to position the insert directly on and / or around the connecting element before the connecting element is placed on and / or in the component and before bonding, in the case of a round or oval cross-section of the connecting element, at least one insert can be at least partially ring-shaped and / or crown-shaped.

[0028]

[0032] Thus, a ring-shaped and / or crown-shaped insert can be arranged on and / or around the outer surface of the connecting element, in particular to prevent displacement and / or to be under tension.

[0029]

[0033] In another embodiment, the at least one insert has at least two centering elements spaced apart from each other.

[0030]

[0034] This ensures that, when the connecting element is positioned on and / or in the component, the component and the connecting element are precisely centered and spatially aligned using the centering elements. If necessary, the centering elements also partially subdivide the adhesive chamber. Thus, the insert with centering elements actively and precisely centers the component and the connecting element relative to each other during positioning and / or assembly. If galvanic isolation between the component and the connecting element is not required, a crimp contour directly on the metal node (connecting element) can alternatively perform the centering and / or sealing function.

[0031]

[0035] A "centering element" is, in particular, any structural element that centers the component and the connecting element during their assembly and / or arrangement. The centering element is specifically designed to enable self-aligning, precise positioning and / or joining of the connecting element in and / or to the component, without hindering the wetting of the minimal adhesive surface by the adhesive when filling the adhesive chamber. The centering element can be, for example, a rib, a web, and / or a spacer. The centering element does not need to have a constant material thickness across its entire dimension but can be specially shaped.Preferably, however, a section of the centering element has a material thickness that precisely separates an inner surface of the component and an outer surface of the connecting element, thus defining the dimensions of the adhesive gap. The centering element is particularly firmly connected to the insert or integrally formed and / or manufactured as part of the insert. One or more centering elements can, in particular, deflect the flowing adhesive within the adhesive chamber and distribute it flatly and widely with minimal turbulence.

[0032]

[0036] In order to provide a uniform, circumferential adhesive gap in the case of a round or oval cross-section of the connecting element, the at least one insert can have at least three centering elements spaced apart from each other.

[0033]

[0037] Thus, three centering elements of the insert, spaced evenly apart, particularly with an average spacing of 120°, can be arranged to ensure a radially and circumferentially uniform adhesive gap. In the case of a crown-shaped insert, for example, it has a circumferential ring that can be slid onto an outer surface of the connecting part, and on which at least three centering elements are arranged perpendicularly and thus spaced in the longitudinal direction of the connecting part.On the side opposite the ring, the insert has, for example, a circumferential O-ring or a lamella as a sealing element at the end of the centering elements, so that after inserting the connecting part with the attached crown-shaped insert into a component, the adhesive chamber is formed between the ring and the sealing element of the insert and the inner wall of the component and the outer surface of the connecting part.

[0034]

[0038] In another embodiment, at least one insert is materially, force- or form-fit connected to the component or the connecting element before the materially bonded connection of the component and the connecting element.

[0035]

[0039] This ensures that the insert is spatially fixed to the component or connecting element before assembly and joining, thus preventing it from shifting during assembly.

[0036]

[0040] To spatially fix the insert during arrangement and / or joining, the at least one insert can be at least partially accommodated in an insert recess in a surface of the component and / or the connecting element.

[0037]

[0041] In principle, the insert acts as a separating and / or insulating link between metals with different electronegativity values ​​when arranging and / or joining the fastener and the component. When joining isotropic materials with different electronegativity values, the fastener can therefore be designed in two parts, with a non-conductive insert being inserted into the receptacle of the metallic fastener by means of a force-fit and / or positive fit. This non-conductive insert ensures the defined insertion and / or insertion of the fastener and the component relative to each other and, together with at least one seal, provides a force-fit connection after the fastener has been arranged and / or joined to the component. Furthermore, the insert prevents the transfer of electrons from the less noble to the more noble electrically conductive material.Thus, the insert between the connecting element and the component acts as an electrical insulator. In principle, an insert can also be a guide element.

[0038]

[0042] In another embodiment, the device has a second opening for venting the adhesive from the filled adhesive chamber and / or a second sealing element for limiting the filled adhesive chamber.

[0039]

[0043] The adhesive chamber can be sealed on two opposite sides by means of two sealing elements. This improves the sealing of the adhesive chamber. Furthermore, due to the elastic properties of the seals and their spatial expansion during filling, a slightly larger volume of adhesive than the available volume in the unfilled adhesive chamber can be introduced. This ensures complete filling of the adhesive chamber even in the case of undercuts or unfavorable flow conditions resulting from the shape of the component and / or the connecting element. Gas can escape from the adhesive chamber through a second opening accessible from the outside, either directly or via a channel connected to the adhesive chamber.This makes it possible to visually inspect the outlet opening to determine and control whether the adhesive chamber is completely filled with the adhesive.

[0040]

[0044] In another embodiment, the at least one insert part has at least one opening accessible from the outside, a second opening and / or at least one channel for receiving the adhesive.

[0041]

[0045] In addition to defining the adhesive chamber, a single insert can multifunctionally perform the mechanical centering of the component and the fastener relative to each other, ensure a homogeneous adhesive gap, provide galvanic isolation and sealing between the component and fastener, fill the device with adhesive, and vent the adhesive channel. Consequently, all these complex functions can be integrated into a single insert or multiple inserts. This allows the fastener to be geometrically simple, particularly without bores or undercuts, and therefore manufactured using cost-effective primary forming processes such as forging and / or casting, while the insert itself can be produced, for example, by injection molding. The insert can also incorporate one or more integrated injection and / or venting channels.

[0042]

[0046] In order to provide a defined sealing fit for the respective sealing element, the connecting element, the component and / or the at least one insert can have a recess for at least partially receiving a sealing element.

[0043]

[0047] A "recess" (also called a "groove contour") is, in particular, a recessed space in the surface and / or material of the fastener, the component, and / or the at least one insert. A recess can be a depression and / or a groove. Because the sealing element is at least partially accommodated in the recess, it is spatially fixed during the arrangement and / or joining of the fastener and the component.

[0044]

[0048] In another embodiment of the device, the at least one sealing element is arranged at least partially in a gap between the component and the connecting element and / or the at least one insert, serving as a tolerance compensation means and / or damping means.

[0045]

[0049] Thus, a seal and / or insert can be designed at one end of the bonding surface to compensate for tolerances between the butt surfaces of the component and the fastener, or a shoulder of the fastener. This allows the component, for example, a bicycle frame tube, to be or be cut to a customer-specific length. When manually cutting a frame tube to shorten it, there is usually always a slight deviation between the length and the radius of the cut tube. Therefore, there is a slightly different radial gap between the frame tube and the fastener, which is compensated for by the seal and / or insert, for example, a circumferential ring of the insert on its outer surface.It is particularly desirable that the seal be at least partially visible on the outside at the transition between the component and the connecting element. Furthermore, by extending the seal and / or the insert outwards beyond the gap, overflow of the adhesive when filling the adhesive chamber is prevented.

[0046]

[0050] Additionally, the sealing element and / or the insert acts as a damping element and / or crash absorber in the gap between the component and the connecting element. In this design, the cross-sectional area of ​​the sealing element and / or the insert between the edge of the connecting element and the edge of the component is significantly thicker, and during the connection process, this seal receives only minimal preload between the two edges. If an axial force is applied and / or an axial force impulse occurs during subsequent use of the device, such as an impact, the adhesive, the seal, and / or the insert between the edges undergo elastic deformation.

[0051] In order to align the connecting element and the component specifically during arrangement and / or joining to form the adhesive chamber, the connecting element may have at least one guide element for arranging the connecting element on and / or in the component.

[0047]

[0052] Thus, a geometrically defined guide geometry of the connecting element ensures precise alignment between the connecting element and the component and / or effective sealing by means of at least one sealing element and / or the insert during assembly. This, in accordance with the Poka-Yoke principle, prevents faulty joining and / or incorrect alignment of the connecting element to the component. The guide element, or two or more guide elements, is specifically designed to enable self-aligning, precise positioning and / or joining of the connecting element in and / or to the component, without hindering the wetting of the minimal adhesive surface with the adhesive during filling of the adhesive chamber.

[0048]

[0053] The "guide element" is, in particular, a structural element. The guide element can, for example, be a rib and / or a spacer projecting beyond the outer surface of the fastener. The guide element is, in particular, firmly connected to the fastener. For example, the guide element(s) may be directly formed and / or molded onto the fastener during additive manufacturing. However, the guide element of the fastener can also have a complementary counterpart on the component; for example, the guide element and the counterpart may be designed as a tongue and groove. In principle, one or more guide elements can be arranged on the component, either in addition to or instead of being arranged on the fastener.A guide element or several guide elements can be used, in particular, to deflect the flowing adhesive within the adhesive chamber and to distribute it flatly and widely with minimal turbulence. The guide element can also be integrated into the at least one insert.

[0049]

[0054] In another embodiment, the device has a fixing means for spatially fixing the component and the connecting element and / or the at least one insert part.

[0050]

[0055] Thus, in applications where the manufactured device is to be processed immediately after filling the adhesive chamber and / or where waiting for the adhesive to cure is not possible, the fixing element allows the component and the connecting element to be spatially fixed and their relative arrangement to be maintained despite the incompletely formed bond. The fixing element can be a molded part integrated into the connecting element, a cylindrical pin, a dowel screw, or similar. The cylindrical pin, for example, can be accommodated in a dome in the adhesive chamber and / or on the surface of the component. In this way, the connecting element and the component, aligned after the arrangement and / or joining and application of the adhesive, are temporarily secured and held in position by the fixing element. The fixing element can also be attached to or formed by the insert.

[0051]

[0056] The fixing agent thus represents an auxiliary device with which the connecting element and the component are held firmly together until the adhesive has fully cured. This allows the device to be processed further promptly after the adhesive chamber has been filled and before the curing process is complete.

[0052]

[0057] In another aspect of the invention, the problem is solved by a method for connecting a component to a connecting element, comprising the following steps:

[0053] - Arranging the connecting element on and / or in the component and arranging at least one insert at least partially between the component and the connecting element and at least one sealing element such that a gas-filled adhesive chamber is formed, bounded by the component, the connecting element, the at least one insert and the at least one sealing element, wherein an externally accessible filling opening and / or an outlet opening is or are formed by arranging the connecting element on and / or in the component and / or is or are present in the connecting element and / or the at least one insert,- introducing an adhesive through the filling opening into the gas-filled adhesive chamber,

[0054] - Controlling the adhesive through and / or in the outlet opening so that the adhesive chamber is completely filled with the adhesive, and

[0055] - Forming a materially bonded connection between the component and the connecting element by means of the filled adhesive chamber, so that by means of the at least one insert part a homogeneous adhesive gap and / or a homogeneous adhesive chamber is present between the component and the connecting element .

[0056]

[0058] The assembly process involves, in particular, the joining and / or assembly of the fastener and the component. This joining can be achieved by force-fit and / or friction-fit. However, the fastener and the component can also be loosely arranged next to each other. The assembly and / or joining process creates, in particular, a defined and / or sealed adhesive chamber. The joining of the fastener to the component can be achieved, in particular, by manual insertion force and / or gravity.

[0057]

[0059] The arrangement of the fastener, the component, and the at least one insert, and / or the application of the adhesive, is ensured, in particular according to the Poka-Yoke principle, by consistently eliminating human error, even though both process steps can be carried out in different ways. The arrangement and bonding can be performed manually by assistants with only brief training, semi-automatically with the support of auxiliary devices, or fully automatically by miniature robots.

[0058]

[0060] It is particularly advantageous that, in contrast to the prior art, time-consuming rework, such as straightening, smoothing of welds, and / or trouble-free inspection of the adhesive and / or joining process, is completely eliminated. Consequently, a very cost-effective and reliable manufacturing process with a high processing speed is provided, which is applicable to small, medium, and large-scale production. For example, a precision device with a base area of ​​approximately 2 m², previously welded by highly specialized personnel, can be manufactured using the inventive method. 2The frame, which serves as a support structure for the post-processing of automotive parts, can now be manufactured within just one hour by semi-skilled workers. In contrast, the previous process required 15 hours, primarily due to the complex welding preparation, the welding itself, and post-processing such as measuring and straightening.

[0059]

[0061] In one embodiment of the method, the arrangement can be carried out by forming a positive-locking and / or force-locking connection between the connecting element and the component and / or by using a further sealing element, an insert component with at least two centering elements and / or a guide element.

[0062] The geometrically defined guide geometry, achieved through one or more guide elements and / or the insert with or without centering elements, in combination with at least one seal and / or additional seals, ensures precise alignment of the connecting element and the component during assembly and / or joining. In applications with stringent requirements for form and / or positional tolerances, as well as dimensional accuracy of the fixture, the joining surfaces of the component and the connecting element can be prepared prior to assembly and / or joining using precision machining processes. Alternatively or additionally, the connecting element and the component to be assembled can be held and aligned in a suitable jig and / or holding device.

[0060]

[0063] In the second joining step, the injection of the adhesive, the adhesive is applied through one of the two openings. The adhesive is introduced into the adhesive chamber, primarily under pressure. The displaced air escapes from the adhesive chamber through the outlet opening, and pressure equalization occurs until complete wetting of the bonding surfaces is ensured and the adhesive appears in and / or from the outlet opening, clearly visualizing the fill level of the adhesive chamber. The appearance of the adhesive in and / or from the outlet opening can be monitored in real time by an operator or an optical measuring system. The appearance of the adhesive always signals complete wetting of the defined bonding surfaces and the formation of the desired adhesive gap in the adhesive chamber.After being filled with the adhesive, it then hardens completely, while the adhesive chamber remains tightly sealed during this time.

[0061]

[0064] When using a guide element, sufficient sliding and static friction is formed, in particular between the inner surface of the component and an outer surface of the guide element, to ensure a positive fit.

[0062]

[0065] An activator and / or a cleaner can be applied to the adhesive chamber and / or to the surfaces to be bonded before and / or after the fastener has been arranged and / or joined to the component.

[0063]

[0066] After the adhesive has been introduced and the adhesive chamber has been checked to be completely filled, the filling opening and / or the outlet opening can be closed by a sealing device, such as a cylinder pin and / or a fitted screw, in order to close the adhesive chamber permanently.

[0064]

[0067] After the adhesive has been applied and the filling has been checked, the bonded joint is left in position for a predetermined curing time, and optionally the curing can be accelerated by an increased temperature.

[0077]

[0069] A frame device 101 comprises a component 103 and a connecting element 105. The component 103 is designed as an elliptical tube with an internal cavity and is made of a metal that is incompatible with the different metal material of the connecting element 105. The connecting element 105 has a first opening 113 and a second opening 115. The two openings 113 and 115 are each connected to an internal adhesive chamber 121 via an injection channel 117. The connecting element 105 is partially inserted into the cavity of the tubular component 103 (Figures 1 and 2).

[0078]

[0070] At the inner end of the adhesive chamber 121, a first sealing element 107 is received in a groove contour 111 of the connecting element 105. At the opposite end of the adhesive chamber 121, a second sealing element 109 is arranged at the butt edges of the component 103 and the connecting element 105 (Figure 2). Thus, the adhesive chamber 121 is bounded and sealed by an inner outer surface of the connecting element 105, an inner surface of the component 103, and the two sealing elements 107 and 109. Spaced plastic inserts 119 are arranged on the inner outer surface of the connecting element 105, which is embedded in the component 103. These inserts act simultaneously as insulators between the incompatible metals of the connecting element 105 and the component 103 and as guide elements during assembly. Furthermore, the connecting element 105 has a fixing element 123, designed as a pin, on its inner outer surface (Figure 1).The connecting element 105, which is designed in such a complex way, was manufactured using an additive manufacturing process.

[0079]

[0071] To manufacture the frame device 101, the following steps are carried out in a method for connecting the component 103 with the connecting element 105.

[0080]

[0072] As a preparatory step 303, the inserts 119 are placed into insert recesses (not visible in Figures 1 and 2) of the connecting element 105. Likewise, the first sealing element 107 is placed in the groove contour 111 and the second sealing element 109 is positioned at a butt edge of the connecting element 105. Subsequently, the connecting element 105 and the component 103 are arranged by partially inserting the connecting element 105 into the component 103 (step 305). By this arrangement 305, the gas-filled adhesive chamber 121 is formed by the component 103, the connecting element 105, and the two sealing elements 107 and 109 (step 307). Subsequently, a two-component adhesive 309 is introduced into the adhesive chamber under pressure via the first opening 113 and the injection channel 117.The inserts 119, which also act as guide elements during the arrangement 305, distribute the adhesive evenly within the adhesive chamber 121. Simultaneously, the pressurized filling process forces the air out of the adhesive chamber 121 via the inlet channel 117 and further out through the second opening 115. The introduction of the adhesive 309 continues until a check 311 indicates that the adhesive is detected at the second opening 115. The adhesive is then allowed to cure until a complete, material-bonded connection has formed between the component 103, the connecting element 105, and the sealing elements 107, 109 by means of the adhesive in the filled adhesive chamber.

[0081]

[0073] Alternatively, the insert 119 is crown-shaped. In the illustration of Figure 6, the component 103 is not shown, and the crown-shaped insert 119 is pushed onto the connecting element 105 under tension, such that one outer butt edge of a ring 133 of the insert 119 abuts against an butt edge of the connecting element 105. Four centering elements 131 are arranged longitudinally spaced apart from one another on an opposite inner butt edge of the ring 133. A second sealing element 109 is arranged on a side of the centering elements 131 opposite the ring, which is designed as an annular sealing lip on a sealing carrier 137. The sealing carrier 137 is connected to the ends of the centering elements 131 and forms a seal between the insert 119 and the connecting element 105.Opposite this, the inner butt edge of the ring 133 forms a first sealing element 107 due to its elastic material. Within the ring 133, a first opening 113 (filling opening) and a second opening 115 (outlet opening) are arranged alternately spaced around the circumference. Each opening 113 or 115 is connected via an injection channel 117 located inside the ring 133 to a through-opening 125 at the inner butt edge of the ring 133. The respective passage opening 125 ends in an adhesive chamber 121, which is bounded by an outer surface of the connecting element 105, the centering elements 131, the first sealing element 107, the second sealing element 109 and an inner surface of a component 103 when the component 103 is pushed onto the crown-shaped insert 119 on the connecting element 105 (see state in Figures 7 and 8).To bond these components of the frame device 101, an adhesive is injected through the corresponding first opening 113 and enters the adhesive chamber 121 via the injection channel 117 and the through-opening 125. Since the centering elements 131 have a smaller, decreasing material thickness at their end section, aligned with the second sealing element 109, the adhesive can enter the next area of ​​the adhesive chamber 121 via this beveled section and, after completely filling all adhesive chamber sections formed between the centering elements 131, exit to the outside again at the second opening 115 via the corresponding through-opening 125 and the subsequent injection channel 117.

[0082]

[0074] In an alternative embodiment of the crown-shaped insert 119 shown in Figure 9, it has an annular first sealing element 107 and, opposite it, an annular second sealing element 109, with the centering elements 131 arranged between the two sealing elements 107, 109. In this embodiment, the first opening 113, the second opening 115, and the injection channels 117 are arranged in the connecting element 105, making the connecting element 105 more complex. The first opening 113 and the second opening 115 of the connecting element 105 are flush with the respective injection channel 117, and the through-holes 125 are arranged in the outer surface of the connecting element 105. The first sealing element 107 of the insert 119 is designed in cross-section as an L-shaped flat gasket, which seals the butt edges of the component 103 and the connecting part 105 to each other (Figure 10).The second sealing element 109 is again designed as an annular sealing lip on a sealing carrier 137. In this alternative, however, the centering elements 131 of the insert 119 have their greatest material thickness in the middle and slope down on both sides with their material thickness towards the first sealing element 107 and the second sealing element 109, so that the adhesive can pass through the respective centering element 131 into the next section of the adhesive chamber 121 on both sides in the area of ​​these sloping sections. Otherwise, in this alternative of the frame device 101, the component 103 and the connecting element 103 are designed as described above and are used together with the insert 119 during bonding as described above.

[0075] In a further alternative of the crown-shaped insert 119 shown in Figures 11 and 12, it is formed in two parts with a ring 133 and a clamping element 135, wherein the clamping element 135 is an open clamping ring and is guided by the centering elements 131. In this alternative, the centering elements 131 have a greater width, and the greatest material thickness is again located in the center of the centering elements 131 in the area of ​​the clamping element 135, with the material thickness decreasing longitudinally on both sides. In this alternative, the injection channels 117 are arranged in the connecting element 105. The insert 119 and the component 103 are sealed to each other by means of a first sealing element 107 designed as an O-ring. Likewise, the second sealing element 109 is designed as an O-ring, which is received in a groove contour 111 of the connecting part 105.The clamping element 135 is arranged circumferentially in the adhesive chamber 121, but has sufficient clearance to allow the adhesive to flow both above and below the clamping element 135. In this two-part embodiment of the insert 119, the ring 133 is made of an inflexible material, while at least the clamping ring 135 is made of a flexible material.

[0083]

[0076] Alternatively, a component 203 and a connecting element 205 form a linear profile device 201. Here, the connecting element 205 has a groove contour 211 at its end, in which a first sealing element 207 is partially received. A second sealing element 209 is arranged on an inwardly facing, lower surface of the connecting element 205. The component 203, which has an arc-shaped cross-section, rests on the first sealing element 207 and the second sealing element 209 (Figure 3). A guide element 219 is arranged between the inner surfaces of the connecting element 205 and the component 203, and an adhesive chamber 221 is formed above the guide element. As shown in Figure 4, two guide elements 219 are arranged longitudinally spaced apart from each other by way of example.A first opening 213 for filling the adhesive chamber 221 and a second opening 215 for the adhesive to exit the adhesive chamber 221 were created by the arrangement and shape of the component 203 and the connecting element 205 relative to each other.

[0084]

[0077] The connecting element 205 and the component 203 have been manufactured in a joining process analogous to the one described above, wherein the insertion of an insert part during the manufacture of the linear profile device 201 is dispensed with, the guide elements 219 are formed directly as a contour of the connecting element 205 and an adhesive metering device for introducing the adhesive into the adhesive chamber 221 is arranged flush at the first opening 213.

[0085]

[0078] In an alternative version of the linear profile device 201, the insert 219 is formed in one piece and has four centering elements 231 (Figures 13 and 14). The insert 219 is made of an elastic material, such that its outer surfaces form a first sealing element 207 and a second sealing element 209. The bent section of the component 203 is arranged and centered between the opposing centering elements 231, so that an adhesive chamber 221 with a defined, predetermined volume is formed. Alternatively, the linear profile device 201 is filled with adhesive and used as described above.

[0086]

[0079] Thus, a method 301 for connecting a connecting element 105, 205 with a component 103, 203 and various devices 101, 201 are provided, in which, due to a precise material-bonded adhesive connection by means of a formed, limited and sealed adhesive chamber 121, 221, a device 101, 201 that can withstand long-term static and dynamic loads is provided.
